What This Tool Does
Sapling AI Detector is a free, browser-based tool that analyzes text for AI-generated content. Paste any document and receive an instant AI probability score along with a sentence-level breakdown showing which parts of the text are most likely machine-generated.
The tool is designed for anyone who needs a quick, no-friction first check — students verifying their own drafts, educators screening submissions, content managers reviewing freelance work, and writers checking AI-assisted copy before it goes to a client.
AI Probability Score
Instant 0–100% score on any text, based on perplexity and burstiness signals.
Sentence-Level Analysis
Each sentence is scored individually so you can identify exactly which lines are flagged.
No Account Required
Free to use with no sign-up, no email, and no text stored after your session ends.
Who This Tool Is For
The tool is built for four main groups:
- ✓Students who want to self-check before submitting to avoid unexpected flags from institutional detectors.
- ✓Educators and institutions who need a free first-pass screen on student assignments before escalating to formal review.
- ✓Content managers who review freelance submissions at volume and need a quick authenticity check before publishing.
- ✓Writers who use AI-assisted drafting and want to see how their revised output reads to detection systems before sending to clients.
Limitations You Should Know
AI detection is a probabilistic process, not a definitive test. The score represents statistical likelihood, not proof of authorship. Key limitations:
- ⓘ False positive rate on human writing is 12–17% — polished, grammatically consistent writing may score higher than expected
- ⓘ Accuracy on texts under 50 words is unreliable — submit at least 150 words for a meaningful score
- ⓘ Heavily edited AI text is significantly harder to detect than raw output
- ⓘ ESL (non-native English) writing may produce elevated AI scores due to simpler sentence structures
- ⓘ Detection results should never be used as sole evidence in academic or professional disciplinary decisions
